Similar to brownie points, except instead of simply gaining favour with a person, you gain an increased chance of being granted permission to have anal sex with that person.

This term is derived from an ancient Spartan courting tradition, where women were not allowed to marry a man until he had completed his military training, however the women had to remain virgins until married.

In order to secure the continued attention of a suitable spouse, it was extremely common for Spartan women to please their prospective partner with anal intercourse.
